wrought seamless steel pipe

The manufacturing process for wrought steel pipe works raw steel into tubes of various lengths and diameters. Steel pipes play a role in the underground moving of water and gas, encasing electrical wires for protection, and the production of vehicles, bicycles, plumbing and heating systems, street lamps and refrigeration units. Welded and seamless wrought steel pipes often go through a machine for straightening. Threads machined into the ends of smaller diameter pipes allow them to connect together. Various protective coatings placed over the steel -- such as oil, paint, zinc or other kinds of material depending on the usage of the pipe -- prevent rusting.
